DES-7200 Configuration Guide Chapter 6 BGP
Configuration
6-10
Command Function
soft-reconfiguration inbound
information sent by the BGP peer
(group).
DES-7200(config-router)# neighbor
{address | peer-group-name}
route-reflector-client
(Optional) Configure this switch as
the route reflector and specify its
client.
DES-7200(config-router)# neighbor
{address | peer-group-name}
shutdown
(Optional) Disable the BGP peer
(group).
Use the no mode of above commands to disable the configurations.
If one peer is not configured with the remote-as, each of its members can use the
neighbor remote-as command to configure it independently.
By default, each member of the BGP peer group will inherit all its configurations.
However, each member is allowed to configure the optional configurations which
have no effect on the output update independently to replace the unified
configuration of the BGP peer group.
Caution
Each member of the BGP peer group is allowed to configure the optional
configurations which have no effect on the output update independently to
replace the unified configuration of the BGP peer group. That is to say, each
member of the BGP peer group will inherit the following configurations:
remote-as 、 update-source 、 local-as 、 reconnect-interval 、 times 、
advertisemet-interval 、 default-originate 、 next-hop-self 、 password
remove-private-as、send-community 、distribute-list out、filter-list out、
prefix-list out、route-map out、unspress-map、route-reflector-client.
The neighbor update-source command can be used to select any valid
interface to establish the TCP connection. The key function of this command is
to provide available Loopback interface, which makes the connection to the
IBGP Speaker more stable.
By default, it is required to directly connect with BGP peers physically to establish
the EBGP connection. To establish the EBGP peers among non-direct-connected
external BGP Speakers, the neighbor ebgp-multihop command can be used.
Caution
To avoid route loop and oscillation, the EBGP peers who need multiple hops to
establish BGP connection must have non-default routes to each other.
For the sake of the security, you can set the authentication for the BGP peers
(group) which will establish the connection, the authentication uses the MD5
algorithm. The authentication password set for the BGP peer should be identical.
